invention isf-'directed to an ,improvement in apparatus for facilitating the maintenance of endotracheal anesthesis, and Ais particularly designed with a view to relieve the anesthetist as well as the patient of objectionable, though heretoforeznecessary, disadvantages inthe use of such an apparatus.

As heretofore more or less conventionally practiced, the anesthetist .encounters diiculty in maintaining the inhalation valve vconnected .to the tracheal catheter; and usually seeks to avoid this diiculty by holding .the vinhalation valve with gauze lor with `tape connected tothe operating frame, .or :by holding the apparatus with the handv over the face of rthe patient during the period of operation. Either Iof these-methods is uncomfortable, one to the patient who hasto sustaina stripof gauzeor tape, and the other to the anesthetist, who Afor the vreason of his attention .being directed `rto theholding of the apparatus in the face o'f Ithe patient nds it virtually impossible to devote his attention to his other Aand probably more important duties, as for exampie, in determining the arterial' tension, Vthe pulse, and the breathing of the patient.

The primary object of the present'invention is .the 'provision of means, whereby,vonce the surgical ,degree ofnanesthesis has been 4.obtained and the apparatus applied` to the vtace Aof the patient, the necessary parts, provided in themselves for relative adjustment as may be required, are more or less rigidly supported, relieving the anesthetist of his duties in connection with such holding and vpermitting him to be practically free to devote his attention to his other mentionedand important duties.

The inventionlis illustrated in the accompanying drawings, in which:

"Ihe improved apparatus includes :a vhollow base l, of box-like form, having a top 2 secured inl place in a man-ner -to permit its convenient removal. The top 2 carries ,a U-shaped conduit 3, the: respective. ends of which open through the top. One of the open ends of the conduit 3 is provided with a 7flexible gasket 4 to removably receive and sealconnectionwith a nipple 4 depending from the inhalationV valve, indicated .at A. The upper surface of the top 2 and the .corresponding formation of the top of the base is formed to provide va downwardly inclined section4 2", terminating at its vends inan upstanding flange' by'means ofi-a tting 2", the upstanding flange providing for supporting the inhalation vvalve A beyondits .connection with the conduit 3.

The inhalation valve,-s o called, is hollow in Y form, connected-atone branch end with the mask andthe other; branch end with the tubes that extend tothe apparatus. The inhalation valve is conventional in apparatus .of this type, forms no part of the present invention, .and requires no particular showing or description.

The lower portion -of the hollow base t is formedwith spaced walls rl. To the .bottom surface; o f the lowermostof the said walls is secured an elastic :sheet 3 a5 rubber, -to rest upon the support C, to which the apparatus is .temporarily secu-red.v One of ther walls of the hollow base in Ythe plane :of the lspace -between the walls l is vformed with openings 9 lto receive an appropriate and conventional securing member It, by which the :base isY'removablyA fixed Lto the support C.

Ehe remainingoutlet .of the cond-uit 3 is .threaded org otherwise `*formed to. removably re- -ceiye and supporta nipple lL-andtiie upper-'end ci the nipple formed lon its inner surface with a rubber gasket |52. .From the supply tube, .carried by and .supported lby the nipple -I l, leads a Pureerably :curved tubular section il', rJtted within .and irictionally angagii'lg the gasket I2 of the nipple Il, the opposite end of the section :Iy' receivingA animale 41.8., in turn connecte-d` to a flexible hose section I9, preferably externally reinforced against collapse. The opposite end of the flexible hose section I9 is connected to a nipple 20, fitted within one end of a metallic sleeve 3 2|, the opposite end of which receives a metallic elbow section 22, the free end of which elbow section is tapered to receive the appliance B, which in view of the description of the present invention is of course a catheter for endotracheal anesthesia.

To relieve the anesthetist of the objectionable unnecessary duties heretofore referred to, the apparatus includes means by which the supply tube may be adjusted in substantially any desired D- sition and fixed in that adjustment at the desired stage of operation.

The nipple II, which is of course a rigid member and of suflicient length for the purpose, is provided with vertically aligned bearing lugs I3 and I4, into which is iitted, for convenient free rotary movement and removal when desired, one end of a rod I6, which is preferably curved somewhat in accordance with the curvature of the section Il' of the supply tube. One of the lugs, as I3, for example, is provided with a set screw I5, by which the rod I6 may be held in xed rigid relation with the nipple II, the rod being preferably provided with a collar to limit its vertical position relative to the bearing lugs. The end of the rod I6 is formed or provided with a circular disc-like section 29, to which, through the medium of a pivot pin 3 I, is connected a similar disc-like section 32, carried by one end of a rod 33, the disc members constituting an adjustable rotary connection in one lane of the adjacent ends of the rods I6 and 33. e disc 29, on its face adjacent the disc 32, is formed with a circular series of depressions 30, opening through that face, and the proximate face of the disc 32 is formed with a through opening, with which any one of the depressions 39 may register.

A pin 34 isslidably mounted in the opening in the disc 32, and adapted to be operated to engage with or free a particular depression 30 of the disc 29, it being apparent when the pin engages any one of said depressions, the discs are locked against relative rotary movement, while when the pin is free of a depression, the discs are arranged for free rotary movement. The pin 34 is carried on a nger lever 35, pivotally supported in a bracket 3B, depending from the rod 33, a spring 31 being arranged to normally maintain the lever in position to hold the pin in engagement with a selected depression 30.

The end of the rod 33 remote from the disc connection described is formed with a longitudinal bore to slidably receive a rod 39, a set screw 38 carried by the rod 33 serving to i'lx the rod 39 in any desired longitudinal relation to the rod 33.

A metallic sleeve member 2| is provided with a lateral pivot pin 23, on which is mounted a securing and adjusting element, shown more particularly in Figure 11, for the free end of the rod 39. This element includes a sleeve section 24, rotatable on the pin 23 and Xed with relation thereto at will by a set screw 26. The end of the pin 23 is provided with a removable headed engaging element 25 to prevent longitudinal movement of the sleeve section 24 on the pivot pin 23. A second sleeve section 2'I is secured to the section 24 at right angles thereto and receives the free end of the rod 39. A set screw 28 is arranged to x the rod 29 with respect to the sleeve section 21 at will.

The conduit 3 is preferably provided with an .4 outlet at its bottom section, normally closed by a removable cap 6. The flexible section I 9 of the supply tube may, if desired, be formed as shown in Figure 12, wherein the nipples I8 and 20 are formed respectively of U-shaped end-s presenting relatively two connecting sections I8 on the modied nipple, here indicated at I 8', and two inlet sections 20" on the nipple 20. This provides for two flexible sections, here indicated at I9' for obvious advantages in use and installation.

It will be apparent from the above that the necessary elements of the apparatus are supported from the hollow bas I and are arranged to permit relative adjustment necessary to provide proper positioning of the parts as may be necessary in the operation, and that when so adjusted and fixed, the anesthetist is relieved from the necessity of holding the mask with tape or by hand on the face of the patient, as the complete necessary holding is automatically carried out by the details described, with such details permitting all and any necessary operations or relative movements that may be from time to time required. f

What I claim is:

l. A support for use with a supply pipe of an apparatus for administering an anesthetic, with the supply pipe of the type including rigid end sections and a flexible intermediate section, to be held in adjustable relation relative to the apparatus, said support including a first inflexible end section rotatably mounted on one rigid end section of the supply pipe, a second inilexible; section secured to the iirst inflexible section for any desired angular relation of the inilexible sections, a rod slidable in the second inflexible section, a metallic sleeve on the end of the flexible section of the supply pipe, a nipple slidable on the sliding rod and swingingly mounted on and relative to the metallic sleeve, and means for ilxing at will the metallic sleeve and nipple relative to the parts with which they cooperate.

2. A construction as dened in claim 1 wherein the nipples are at right angles to each other and relatively rigid.

3. A construction as dened in claim 1, wherein manually controlled means are provided to x the respective inflexible sections in any one of a plurality of angular relations.
